A plate I2 locking `the operating handle or other member lying against the faceof the block retains the disc l against movement.

Coins are conveyed to these recesses formed by the side of the notch, the Curved Sur through the Slot 9 formed 1n the blOCk l0 Wlllllln face of the coin actingas a cam to urge the coin which the disc is rotatably mounted, the COIlS "deeper into the c'oinr'ecess. Being seated upon passing from the slot to the recesses as they come shoulder I3,V the detent will likewise be `moved in registration upon rotation' of the disc. Each radially inwardly andout of the notch. Since detent, the end of the detent will pass entirely clear of the side of the notch and continued motion may be imparted to the disc. The closely conning wall of the socket maintains the detent in its inner position until it has again returned to the notch. The releasing action is repeated with each coin recess into which a coin is deposited.

` At a point diametrically across the socket from the notch, a passageway 24 is provided inthe block llli) for the discharge of coins from the recesses 8. As each recess passes this point, it falls, under the action of gravity, from the coin recess and through the passageway 24 into receptacle 25. For convenience the receptacle 25 may be placed to one side and a coinn chute 26 be utilized to convey the coin thereto. It will be noted that the passageway is Vonly'as deep as a coin so that a detent passing at this point is.

maintained by the wall of the socket in its inner position.

e While the disc may be attached to the parts with which it is to be associated, in any desired manner, the present mode of attachment shows the mechanism in conjunction with the delivery mechanism disclosed in my copending application, Serial No. 659,587, led March 3, 1933. The

' disc "i may be keyed to the hub 2l projecting ythrough the block and into the socket from the cam 28. A crank 29 disposed at the opposite side of the disc from cam 28 has a driving connection with the hub as by the interlocking lugs 3l. A bolt 32 passing through the crank center, cam hub 2l, and cam 28 retains these parts against -axial separation.

`It is further vto be'noted that rthe bolt 32 holds the entire mechanism in assembled relation. The

`plate I2 may be placed against a side Wall 33 of the casing which encloses the mechanism, the

crank center passing through an aperture Vinthis side wall. A flanged enlargement 34 at -the center of the crank bears against the exterior surface of the side wall, and a face of the cam 28 bears 'against the rearward surface Vof the block I0.

r'Thevblock I6, plate I2, and side wall 33 are 'therefore confined against each other by the securing bolt 32. Removal yof this single bolt 32 permits complete vdisassembly of the mechanism.

In the event that an undersized object Aas an improper coin is inserted, the detent will 4not be depressed below the side 23, with the result that the device will remain locked and an' article will not be delivered.l To enable removal of the improper coin, a passageway 35 is formed in the block l. This passageway is directed toward the vcoin recess 8 so that a rod urged forward through the passageway will push against the detent or against an object seated lon the shoulder I3, and will depress the detent below the side 23 so that the disc 1 maybe rotated. The

"improper'object will drop out through the `open- -ing 24, andthe device will Vagain be in operating condition. Since the block lil is inclosed by the casing of which the side wall 33 forms va part, access tothe block iB and the passageway 35, can only be had by an authorized person.

I claim: f

1 In a coin controlled mechanism, a supporting frame, a member rotatably mounted in the frame and having a coin receiving recess opening radially and an undercut guideway opening vtinto the recess, said 4guideway emending radiy ally of the rotatable member and opening across the center of the coin recess to the periphery of the rotatable member, means for rotating said member, a locking element having reciprocatory motion within the guideway and being retained therein by the undercut formation of the guideway, said locking element having a lug projecting into the coin recess and providing a coin seat on which a coin may rest, said locking element being movable outwardly from the rotatable member into locking lengagement with the frame, means for urging said element outwardly relative to the rotatable member and said frame providing a presser surface against which a coin carried on "said coin seat may ride as the member is rotated to 'force the I.coin and thereby the locking element inwardly to disengage the locking element from the frame.

2. A coin controlled mechanism according to claim 1 in which the portion of the locking element projecting beyond the rotatable member is faced ofi at a .diameter of a coin to be carried y on said seat to provide a flat radially disposed striking face.

3. In a. coin controlled mechanism, a supporting 'block having a circular socket in one face thereof, a coin slot extending along said face and opening into said socket, and a notch at the junction of the coin slot and the socket, a rotatable disc positioned in said socket and having its outer face flush with said face of the block, said disc having a coin receiving recess in its outer face for communication with the coin slot and also having a guideway opening into the coin recess, a locking element reciprocably mounted in the guideway and having a lug projecting into the coin recess to provide a coin seat, said element being movable radially outwardly with respect to the disc and into locking engagement with said notch, means for urging said element outwardly with respect to the disc said `rblock providing apresser surfaceagainst which a coin carried 'on said seat may ride as the disc is rotated to force .the coin and. thereby the locking element inwardly to disengage the locking element from the block, a plate tting against the outer Lfaces of the block and disc and provid-ing the vouter wall of vthe coin slot, said socket, and -said coin recess, and means extending through the plate for rotating said disc.

4. A coin controlled `mechanism according to claim 3 in which a bolt extends through dthe block, disc, and rotating means to retain the parts in assembled relationship.

5. In a coin controlled mechanism, a supporting block providing an abutment, a coin receiving member movably mounted in said block, means for driving said member, a locking element carried by 'said member and having a coin seat, said element being movable with respect Vto said `member into contact with said abutment to limit movement of the member, means for urging said element into Contact with said abutment said abutment serving as a presser surface to contact with .a coin carried on said seat and move the locking element out of contact with the abutment upon movement of said member, said block having a passageway permitting access to said locking element for vicarious manipulation of said element.
